lNCANDESCENT.GAS-BURNER.

SPECIFICATION forming part of Letters Patent No. 662,321, dated November 20, 1900.

Application filed October 20, 1899. SerialNo. 734,184- (No model.)

burners of the type wherein the mantle or hood is sustained by a support located within the same. The principal objection to incandescent gas-burners of this type has been due to the overheating of the central support.

It is the object of my invention to provide an incandescent gas-burner having a central support for the mantle or hood and wherein overheating thereof will be avoided.

In carrying my invention into effect I make use of a tubular central support for the mantle or hood and so mount the support in the burner as to cause the flow of air to be constantly maintained through the same.

In order that the invention may be better understood, attention is directed to the accompanying drawings, forming a part of this specification, and in which- Flgure l is a vertical sectional view of a well-known form of incandescent gas-burner equipped with my present improve ments,and Fig. 2 a plan view looking down upon the end of the central tubular support.

In both of the above views corresponding parts are represented by the same numerals of reference.

While the burner shown in thedrawings is a convenient type for purposes of illustration, it will be understood that my improvements may be used in connection with any burner having an incandescent hood or mantle and which it may be desired to support from the interior thereof.

The Bunsen burner 1 supplies the proper mixture of gas and air to a chamber 2, the top of which is formed of wire-gauze 3, supported by a removable sleeve 4. Located within the chamber 2 is a tube 5, which communicates with the outer air within the usual perforated supporting-body 6. The tube 5 preferably extends up to a point substantially flush with the gauze 3, said tube beingcounterbored at its upper end at '7, as shown. 8 is a baffiing plate or spreader carried by the tube 5. When the tube is counterbored, as explained, the bottom of said counter-bore forms a shoulder 9. 10 represents a central support which is carried within the tube 5 and rests at its bottom upon the shoulder 9. The support 10 is tubular in form and open at its upper end. It sustains the mantle or hood 11 in any suitable way-as, for instance, from a light cross -piece 12, which extends across the usual ring 13 at the top of the mantle or hood. The cross-piece 12 may restin a notch 14, formed at the top of the support 10.

It will be observed that in operation the heating of the central support 10 will result in the creation of a draft therein, and the air passing through the tube will keep it cool and effectively prevent any injury from overheating.

Having now described my invention, what I claim as new, and desire to secure by Letters Patent, is as follows:

1. The combination with a heating-burner and an incandescent mantle or hood heated therefrom, of an im pe rforate tubular support for sustaining said mantle or hood, said support being open at its top and bottom and communicating at its bottom with the outside air, substantially as set forth.

2. The combination of a Bunsen. burner, a chamber above the same, a tube mounted in said chamber and communicating with the outer air, an imperforate tubular support carried by said tube and open at its top and bottom, and a mantle or hood sustained by said support, substantially as set forth.

The combination of a Bunsen burner, a chamber above the same, a wire-gauze section at the top of said chamber, a tube mounted in said chamber and extending through the wire-gauze, said tube being open at its bottom, a tubular support carried by said tube, and a hood or mantle carried by said support, substantially as set forth.

4. The combination of a Bunsen burner, a chamber above the same, a wire-gauze section at the top of said chamber,a tube mount- This specification signed and witnessed this ed in said chamber and extending through the 19th day of October, 1899. wire-gauze, said tube being open at its bot- AARON P STORES tom, atubular support carried by said tube,

5 a hood or mantle carried by said support, and Witnesses:

a spreader within the chamber on said tube, J N0. R. TAYLOR, substantially as set forth. FRANK L. DYER.
